## Our take on Converteo
Reviewed 2026-08-05 by Gabor Kiss against published evidence.

Sharlie, the voice agent behind Orange's Sosh brand, is the most completely documented build in this register, and the detail is the point.

Converteo committed to a voice-to-voice architecture in April 2024, before the model reached general availability, specifically to avoid a later migration off a speech-to-text pipeline—a decision that bought roughly one second of latency against three. Around thirty specialized agents hand off between themselves, escalate to a human, and act on Orange's catalog, billing and account systems rather than only answering. Validation was modeled on how call-center advisors are trained. Virtual clients replay conversations at volume against an LLM-as-a-judge scoring price accuracy and brand posture, and an AI-specific bug bounty ran with around forty white hackers before launch. It went to production on 16 March 2026 with a mechanism to stop it.

The rest of the library is a decade of measurement and pricing work with named clients: Carrefour, Leroy Merlin, L'Oréal, ENGIE, BUT, Picard, Arkema.

The caveat is that this depth is exceptional rather than typical—most of the other cases describe data and marketing engineering, not AI.

### Key strengths
- One engagement documented end to end, including the architecture decision, its latency cost, the evaluation rig and the kill switch—no other agency here publishes at that level
- Evaluation as a discipline rather than an afterthought: virtual clients, an LLM-as-a-judge scoring price accuracy and brand posture, and an AI bug bounty before exposure to customers
- Ten-plus named clients across retail, energy and industry, with the work described case by case rather than listed as logos

### Good to know
- Outside the voice-agent work, most published cases are data and marketing engineering—confirm which practice your engagement lands in
- No headcount, founding year or rates published; scale and price both have to be established in conversation

## Our take on OstraconAI
Reviewed 2026-09-23 by Gabor Kiss against published evidence.

Eleven case studies are published and every client is named, splitting into five internal tools, three AI-assisted outbound campaigns and three strategy or roadmap engagements.

The deployment detail is strongest at Singa: an n8n and Gemini pipeline that enriches, scores and routes inbound leads into HubSpot, live in week three, with a Slack channel for flagging errors and prompts tuned weekly—manual lead sorting went from 45 minutes a day to single-digit minutes.

Nordic Healthcare Group's Azure RAG reference search has been in use since August 2025 and S-Group runs a Copilot Studio planning agent, but neither study publishes usage or accuracy numbers, and every build sits on a platform (n8n, Copilot Studio, Azure, Claude) rather than a model OstraconAI trained or hosts.

The weaker fit is buyers who need custom models, data engineering or AI outside marketing and sales—nothing published goes beyond that remit.

### Key strengths
- All 11 case studies name the client, and most quote a named executive with title—Sanoma Media Finland's Chief Commercial Officer, S-Group's Head of Marketing Strategies, Singa's CCO
- The Gosta Labs study publishes its funnel: 3,930 messages, 198 replies and 62 opportunities across three oncology congresses, with the best campaign near a 19% reply rate
- Handover is part of the delivery: Claude Code training at Barona and Claude training at Olo-apteekki so the client team maintains the tools itself

### Good to know
- Several headline numbers are forecasts or quotes—Attendo is 'about to save' 9,000 hours, Sanoma's 'millions of euros' is an estimate—ask which figures were measured after launch
- The hourly rate on this listing sits well above the European range on our rate index, while the site prices by project and monthly retainer—ask how many hours the retainer buys
- Builds run on n8n, Copilot Studio, Azure, Clay, Apollo and Instantly—ask who owns the workflows and accounts, and who monitors them after the engagement ends

- disclosed specialization in Healthcare / SaaS & B2B
- broader service offering — also covers AI Automation

## Questions buyers ask

### Which has more E-commerce experience, Converteo or OstraconAI?
Both agencies show documented E-commerce work. OstraconAI has the broader industry stack overall, with disclosed experience in Healthcare, SaaS & B2B, FinTech beyond their shared focus.

### Which scores higher overall, Converteo or OstraconAI?
Converteo scores 70.8/100, 10.8 points higher than OstraconAI at 60/100. Both portfolio quality and business credibility feed into the score — see our methodology for the full breakdown.

### Which is faster to engage, Converteo or OstraconAI?
Neither publishes lead times, so this is a read on team size rather than a measured answer. OstraconAI runs the smaller team, which usually means fewer procurement gates and a shorter path to kickoff. Converteo runs a larger one, which tends to mean more steps but more capacity to start parallel workstreams. Current kickoff availability is the number that actually decides it — ask both.

### When should I consider both Converteo and OstraconAI?
Consider running parallel discovery briefs with Converteo and OstraconAI if your project spans multiple workstreams, you want competitive proposals to compare scope and approach, or you're undecided between the specialization angles each brings (see the Best for cards above). Most engagements ultimately go with one — but the parallel-brief phase is a low-cost way to validate fit.
